Our invention relates to an improvement in fasteners for themeeting-rails of sashes, and more particularly to an improvement uponthe device shown in United States Patent No. 466,821, granted January12, 1892, to Edwin H. Ferry, the object of the present invention beingto produce a convenient and effective device, constructed withparticular reference to not only supporting the sashes in a position forventilation, but to locking them in such position.

With these ends in view, ourinvention con- Fig.

sists in a sash-fastener having certain details of construction andcombinations of parts as will be hereinafter described and pointed outin the claims.

Our improved device for fastening the meeting-rails of sashes, consistsof two members,

respectively adapted to be attached to the meeting-rails of the upperand lower sash of a window. The member designed to be attached to themeeting-rail of the upper sash, comprises a base A, provided at itsopposite ends with holes, to receive the screwsB B, by means of which itis attached to the meetingrail 0, of the upper sash. The said base-plateis furnished with a post or stud A, located midway of its length, andadjacent to its inner edge and constructed with a chamber A openinginward. A locking-lever D, adapted at its lower end to be set over thesaid post, is attached thereto by a horizontal pivot E, on which thesaid lever swings. A coiled wire spring F, located within the chamber ofthe post and encircling the said pivot E, .is arranged to engage at itslower end with the base'plate A, and at its upper end with thecross-piece D formed at the lower end of the lever, and made, as hereinshown, to have the exterior configuration of a nailhead. The said leveris constructed midway of its ends, with an elongated slot D at theforward end of which there is a locking ledge d. The extreme upper endof the lever is bifurcated, as at D to receive the beveled tongue G, ofa pivotal finger-piece G, the said tongue being constructed withoperating faces g g, which engage with a plate H, located at the bottomof the said bifurcation D and secured to the outer end of a reciprocaloperating pin H, mounted in the lever, with the length thereof, betweenthe said bifurcation and the forwardend of the slot D so as to move overthe locking ledge (Z, of the lever when it is forced inward by the facesg g of the tongue'of the pivotal finger-piece. The said finger-piece isconstructed at its outer end with an opening G and with a transverselocking-bar G which is substantially square in cross-section. The loweror inner end of the lever is cut away, as at (1', so that when it isfree to be operated by the spring F, it will be inclined from theVertical, sufficiently, as shown by Fig. 3 of the drawings, to cause thefinger-piece G to clear the other member of the fastener, whereby thetwo members thereof will not interfere with the free operation of thesashes when the fastener is not in use.

The other member of the fastener com prises a base-plate I, constructedat its ends with holes to receive screws J J, by means of which it issecured to the meeting rail K, of the lower sash. The said plate I, isfurnished with a large lug L, located midway between its ends, andhaving a straight inner edge L, a curved outer edge L and constructedwith a vertical slot L adapted in width to receive the transverselocking-bar G formed at the outer end of the finger-piece G beforementioned. The said lug is also constructed in its dimensions so that itwill enter the slot D formed in the locking-lever when the same is drawndown over it, as shown in Fig. 2 of the drawings, for locking the sashesin their closed positions. The said lug is also constructed with avertical longitudinal chamber L, which receives a locking-bolt M, havingits beveled outer end furnished with a locking-notch m, whichco-operates with the lockin g ledge d, of the locking lever. The saidbolt is also constructed with a vertical locking-slot M, entering itfrom its upper edge, and under-cut as at M to form a tooth M the upperedge of which is beveled, the said slot M, being situated so that whenthe bolt is retired, it will register with the vertical slot L formed inthe lug. The lower edge of the said lockingbolt is cut away, as at m, toreceive a spiral spring N, one end of which engages with the bolt, whileits other end engages with a vertical pin 0, mounted in the base-plate1, whereby the spring exerts a constant effort to push the boltinto itslocked position, in which it is shown by full lines in the drawings.

In order to lock the sashes in their closed positions, they are movedinto the same, after which the finger-piece G, is grasped and used todraw the locking-lever, against the tension of its spring, down over thelug L, over which the said lever passes by virtue of its provision withthe long slot D As the said locking lever is drawn downward over thesaid lug, its locking ledge (Z, engages with the beveled end of thebolt, and pushes the same inward against the force of the spring Nthereof. Then when the ledge d has passed below the edge of the bolt,the sameis thrown forward by its spring, to engage its notch m, with thesaid ledge, whereby the lever is secured by the bolt in its lockedposition, as shown by full lines in Fig. 2 of the drawings. The sashesare now firmly locked in the closed positions.

It may be here mentioned that in case the.

upper sash was not fully lifted at the beginning of this lockingoperation, it will be lifted into position by the action of the lockinglever on the beveled outer edge of the lug L the construction describedsecuring a very powerful leverage for drawing the sash into position forlocking.

WVhen now it is desired to unlock the sashes, the finger-piece is liftedinto the position in which it is shown by broken lines in Fig. 4: of thedrawings, whereby the faces g g of its tongue press against the plate H,of the pin 11', causing the said pin to be moved inward and engaged withthe bolt, which is thus positively pushed back out of engagement withthe locking ledge cl. After this, the lever is lifted a little to startit, and is then restored to its elevated position by means of its springF.

When it is desired to lock the sashes in a position for ventilation, theupper sash is dropped down, say for two inches, and the transverselocking-bar of the finger-piece e11- tered into the slot L in the lug L,so as to engage with the beveled tooth M of the boltM. The said barbeing now pressed down against the said tooth, the bolt springs back andallows the bar to pass under the tooth, which is then shot over it; asshown by Fig. 5 of the drawings, thus locking the sashes firmlytogether, although they are slid past each other fora short distance,the said locking-bar be ing prevented from turning when thus engagedwith the locking-tooth of the bolt, by reason of its form, which issquare in crosssection, as has been already explained, for the slot L inthe lug is only wide enough to permit it to enter the same. The sashesbeing locked firmly together, may be moved up or down together, so thatventilation may be had at the top or at the bottom of the window, or atboth places as desired. To unlock the windows now, it is only necessaryto press the thumb against the projecting outer end of the bolt, thuspushing the same back, so that its tooth M will clear the locking-bar ofthe finger-piece, and permit the same to be lifted out of the slot L inthe lug. "We are thus enabled not only to support the sashes in aposition for ventilation, but to securely lock them insuch position, sothat the window is as much locked againstintrusion as it would be ifboth of the sashes were in their completely closed positions.

It is apparent that our improved spring-actuated locking lever is notlimited to use with a sash-fastener adapted to be locked in a positionfor ventilation, or vice-versa, and we would therefore have itunderstood that we do not limit ourselves to the exact constructionherein shown and described but hold ourselves at libertyto make suchchanges and alterations therein as fairly fall within the spirit andscope of our invention; We are aware, however, that it is old to providethe lockingthe said lug for locking the sashes in their closedpositions, and the said lever being provided at its outer end with apivotalfingerpiece constructed with an opening in its outer end adaptingit to be engaged with the said bolt for locking the sashes in positionfor ventilation, substantially as described.

2. A fastener for the meeting-rails of sashes, having one of its twomembers furnished-with a pivotal locking-lever, having a finger-piecepivoted in its outer end, and having its other.

member furnished with a locking-bolt adapted to be engaged by thelocking-lever for looking the sashes in their closed positions, andadapted also by its provision with a slot and locking-tooth to receivethe end of the said finger-piece in looking engagement, substantially asdescribed, and whereby the sashes may be locked both in their closed andventilating positions.

3. A sash-fastener having one of its members furnished with a pivotallocking-lever constructed with an elongated slot and a looking ledge,and furnished at its outer end with a pivotal finger-piece terminatingin a transverse locking bar and constructed at its inner end with abeveled tongue, and the said locking-lever being also provided with anoperating-pin arranged to move over its said ledge, and to be acted,upon by the said beveled tongue of the finger-piece, and the othermember of the device having a chambered lug constructed with a beveledouter edge, and with a Vertical slot, and containing a spring-actuatedbolt having a locking-notch to engage with the locking ledge of thelever, and with a vertical slot and locking tooth to co-operate with thelocking-bar of the said finger-piece which enters the slot in the saidlug for that purpose, substantially as set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
